So im finally looking to make the switch to mac for the "user friendliness" as well as the high res screen (thunderbolt monitor). However, I am not sure about what system I can use to for LR, PS Bridge etc. My current PC is a custom i7 8GB ram sytem but im not looking to spend that kind of money. I was considering a used MacBook but they all kind of seem similar but I know you mac folks out there know the difference. Is a 2010 4gb sytem feasible if its going to be exclusively used for video/photo editing? Or do I need to get one of the newer systems. I read a lot of threads about OS issues and software glitches but I don't currently own a mac so I don't understand most of the jargon.
